NOTE 1: Articles of compatibility groups D and E may be fitted or packed together with their own means
of initiation provided that such means have at least two effective protective features designed to prevent an
explosion in the event of accidental functioning of the means of initiation. Such articles and packages shall be
assigned to compatibility groups D or E.
NOTE 2: Articles of compatibility groups D and E may be packed together with their own means of
initiation, which do not have two effective protective features when, in the opinion of the competent authority of
the country of origin, the accidental functioning of the means of initiation does not cause the explosion of an
article under normal conditions of transport. Such packages shall be assigned to compatibility groups D or E.

2.1.2.2 The definitions of compatibility groups in 2.1.2.1.1 are intended to be mutually exclusive, except
for a substance or article which qualifies for Compatibility Group S. Since the criterion of Compatibility Group S
is an empirical one, assignment to this group is necessarily linked to the tests for assignment to Division 1.4.
2.1.3 Classification procedure
2.1.3.1 General
Copyright@United Nations, 2011. All rights reserved.
2.1.3.1.1 Any substance or article having or suspected of having explosives characteristics shall be
considered for classification in Class 1. Substances and articles classified in Class 1 shall be assigned to the
appropriate division and compatibility group.
2.1.3.1.2 Except for substances which are listed by their proper shipping name in the Dangerous Goods List
in Chapter 3.2, goods shall not be offered for transport as Class 1 until they have been subjected to the
classification procedure prescribed in this section. In addition, the classification procedure shall be undertaken
before a new product is offered for transport. In this context a new product is one which, in the opinion of the
competent authority, involves any of the following:
(a) A new explosive substance or a combination or a mixture of explosive substances which is
considered to be significantly different from other combinations or mixtures already
classified;
(b) A new design of article or an article containing a new explosive substance or a new
combination or mixture of explosive substances;
(c) A new design of package for an explosive substance or article including a new type of
inner packaging;
NOTE: The importance of this can be overlooked unless it is realized that a relatively
minor change in an inner or outer packaging can be critical and can convert a lesser risk
into a mass explosion risk.
